Robust Sliding Mode Controller Design for Boost Converter Applications

Abstract

This paper presents detailed steps to design an effective, robust sliding mode controller for boost converter applications. Before that, the paper models a boost converter circuit during a continuous conduction mode (CCM) operation, obtains the related dynamic equations and explains the variation effects of the circuit parameters on the converter performance. The design steps of the proposed controller are illustrated, and the robustness of the controller is demonstrated in terms of maintaining output voltage stability under input voltage variations and load fluctuations. On the other hand, this paper shows a fast and accurate dynamic response of the load voltage during different reference voltages. Simulation results are collected, analyzed, and demonstrated the robustness and correctness of the proposed controller design.
